Objective: to study the effectiveness of using statodynamic exercises for the restoration and rehabilitation of highly qualified volleyball players after a meniscectomy (partial resection of the posterior horn of the medial meniscus). Materials and methods: the study involved 5 players of the Russian Super League on volleyball aged 18-30 years who underwent a meniscectomy (partial resection of the posterior horn of the medial meniscus). To assess the effectiveness of the exercises used, the results were compared with the indices of the control group (CG). The study data of 30 athletes involved in game sports (football, handball, volleyball) with sports qualifications ranging from 1 adult to masters of sports of international class with post-traumatic chondropathy of the knee joints were taken as CG. The average age of the athletes was 25.8±7.2 years, the experience in sports – 12±4 years. To study the subjective assessment of the functional state of the injured knee joint, we used the KOOS scale for assessing the outcome of injuries and diseases of the knee joint. Before and after the ten-day experiment, which consisted of the use of exercises of a static-dynamic nature, the following parameters were measured in the following subjects: the angle of flexion in the knee joint, the volume of the thigh, and static endurance of the quadriceps femoris. Results: The studied EG indices were reliably р<0.05better in comparison with the CG in most of the studied indices, except for the value «Pain» and «Difficulty of performing daily everyday movements». The angle of flexion in the knee joint at the beginning of the experiment was 121±2° and after the experiment significantly (p<0.05) changed to 140±4°, which indicates an increase in the mobility of the knee joint of the injured limb. At the same time, a significant (p<0.05) increase in the volume of the thigh from 41.2±2.7 to 41.8±3.0 cm occurred, which indicates hypertrophy of the muscle fibers of the thigh. At the same time, the strength indices of the quadriceps femoris muscle were significant (p<0.05), as evidenced by the increase in the ability to hold a straight leg with a weight of 2.5 kg in the Leg Extension simulator from 24±7 to 75±13 seconds. Conclusions: The data obtained may indicate that the use of long-term statodynamic exercises in the functional postoperative period (10-21 days) of rehabilitation is an effective (from the point of view of time) means of restoring the knee joint of highly qualified volleyball players after partial resection of the posterior horn of the medial meniscus.
